The Schedule'refex-red to in these Lettera Patent and making part of theBama. K

To all persons to whom, these presents may come Be it known that I,GEORGE DRAPER, of Hopedale, in the town of Milford, of the county ofVorcester, and State of Massachusetts, have made a new and usefulinvention, having reference to Spinning-spindles, their Steps and Gaps;and I do hereby declare the same to be fully described in the followingspecification, and represented in the accompanying drawings, of which-Figure 1 is a front elevation, and

Figure 2, a vertical section of a spindle, with its step and the capthereof, as provided with my invention.

In the carrying out of my invention, as exhibited in such drawings, thespindle is formed with a shoulder,

. to project over and below the mouth ofthe cap, which covers the stepof the spindle; andthe cap is also made so as to rest on and projectwithin the step and cover, or extend down by the joint, or space, whenthere is any, between the cap and step, in order to actas a cutoli", orguard, to preventoil from being thrown out of the cap, or step, andthrough their joint.

The purpose of the shoulder formed on the spindle, so as to project overand below the mouth of the upper end of the cap, is to prevent thelodgment of lint, or fibrous or extraneous matters, between the spindleand the cap, or the mouth of the latter, so as to obstruct theoperations of the spindle. v

In the said drawings', A denotes the spindle, as made with a longcylindrical pivot,f, extended from a shoulder, c e, which is concave, sothat, when'the spindle is in place in the cap, such shoulder shall notonly-cover the mouth,'or opening of the upper-'end of the cap, butextend below it, in man-ner as represented in iig. 2.

The step is shown, at B, as constructed with a cylindrical oil-chamber,b, open at top, and provided with a composition or brass bearing, a,which screws down from the bottom of the chamber b, and into the step.

The pivot f of'the4 spindle enters and rests on the -bearing a.

The cap'G ,is supported on the top of the'step B, and

constructed with a ange, g, to extend down into the chamber b, andagainst its periphery, so as to cover the joint 71., between the cap andthe step, oract as a guard, to prevent oil in the chamber b, while thespindle may be in rapid revolution, from being driven, bycent-ritiigal'ibrce, out of the chamber, and through the 'oint h. J lhesaid cap has also a cylindrical chamber, c, which is open at bottom,there being a passage, el, leading out of the upper part of such chamberand the cap, such passage d having a diameter somewhat greater than thatof the pivot f of the spindle.

Each of the spindle-step caps, shown and' described in the United StatesPatents,N os. 44,265, 81,7 32, and 66,017, extends down outside of itsstep, and below its top, and in consequence thereof, theoil is liable tobe thrownv upon the top of the step, and to work down through thejoint,'between the cap and the step.

My invention diers from such, in having the ange g to extend down withinthe step.

Furthermore, when the passage d ofthe cap has a diameter greater thanthat of the part of the spindle which extends through it, I cover thetop of such pasi any respect, no friction will be generated between thetwo, while the spindle may be in revolution.

In Patent No. 66,017, the cap is so connected with the spindle as torevolve with it, but in my arrangement the cap is stationary while thespindle may be in revolution.

I make no claim to either of the devices, combinations, or arrangementsof parts, as represented in either of the aforementioned patent.. y

' I am aware that the step of a spindle has been made to extend up intoa trumpet-mouth, or flange formed on the spindle, the same being inmanner as represented in Andrew Harriss application for a patent,led'April 5, 1841, and withdrawn November 8, y184:1.

I am also aware that the cap of a spindle-step has been made to rest andlit on the upper edge of, and also has had a flange to extend within thestep, and belowthe joint between the step and the cap, such being asshown in the specilication of Richard A. Eddys application for a patent,rejected April 28, 1851; therefore, I make no claim to such.

-My invention has special reference to a spindle and' step, as providedwith a cap.

The chamber c in the ca made with a diameter greater than that of thespindle-mouth d of the cap, and, as a consequence, greater than that cfthe pivot f, should'be of such a size as to so insulate the ange g fromthe pivot f, as to prevent oil that may rise on the pivot from thebearing a., or may be descending on the pivot, from being forced againstthe ange g, and between it and the step. rlhis chamber c, with theflange g therefrom, is productive of advantage. vglhe extension of theupper end of the cap 'up into the spindle, also prevents brous mattersand dirt from getting into the mouth of the ca ,and thence into thedeluge-insulating chamber c.

I claim the cap, C, as formed, with the insulatingchamberc, and extendedup into the conical shoulder e of the spindle, and down within the step,(by means of the flange g,) the whole being substantially as explained.l
